Recently, while helping a relative involved in cross-border trade organize the accounts, we encountered a troubling issue. He complained: "The process of querying the Blockchain Transaction History is more cumbersome than flipping through old newspapers. Although it is advertised as immutable, finding a transaction record from six months ago actually takes half an hour to retrieve."

At that moment, my phone popped up a piece of tech news, in which the term "Lagrange" caught my attention. The subtitle claimed "Distributed storage speeds up by 300%", which immediately piqued my interest.

As a computer science graduate, I delved into Lagrange's technical white paper. Its underlying logic is refreshing. The "difficulty in auditing" problem complained about by my relatives actually stems from the inherent flaws of traditional Blockchain storage: data is like files piled up in a corner of a warehouse, requiring a linear search from start to finish for each retrieval, which is known in the technical field as the "linear access bottleneck of chain storage."

Lagrange adopts an innovative approach to solve this problem. It breaks down the data into numerous encrypted fragments and stores these fragments in the "distributed hard drives" of global nodes. This is like tearing a thick book into sticky notes and placing them in different locations. When a specific piece of content needs to be found, the system can simultaneously retrieve data from multiple locations. This technology, known as "sharded storage + parallel retrieval," can theoretically reduce data reading speed to the second level.

To verify the actual effectiveness of Lagrange, I conducted an experiment during the second reconciliation two weeks later. I migrated some transaction data from my relatives to the Lagrange test network. Surprisingly, what originally took 27 minutes to complete the tracing of cross-border transfer records was finished in just 4 minutes this time.

This groundbreaking advancement not only greatly improves the efficiency of data retrieval, but also brings new possibilities for transaction history management in cross-border trade. The application prospects of Lagrange technology are broad, and it is expected to pave the way for the further popularization of blockchain in the commercial sector, especially in scenarios that require fast and accurate data retrieval. With the maturity and promotion of this technology, we can expect to see more fields benefit from it, injecting new momentum into the development of the digital economy.
